50], observed by LINEAR on Apr 23 and by LONEOS on Apr 26, and then found observations back to March 3 [IAUC 7624, 2001 May 14].
Spahr, Minor Planet Center, identified asteroidal observations of the object in LONEOS and LINEAR data back to Feb 2 [IAUC 7629, 2001 May 21].
Skiff, Lowell Observatory, reported his discovery of a 16th mag comet on images taken with the LONEOS 0.
An apparently asteroidal object of 19th magnitude reported by LONEOS (observer W.
To date [2000 May], the LONEOS project has discovered 33 near-Earth asteroids and 8 comets.
Williams also identified LONEOS observations of the object on April 10.
Dalcanton subsequently forwarded single-night LONEOS observations obtained on March 28 and found by G.
acquired more images of the rapidly receding, fading object on September 29th, and so did amateur astronomer Peter Birtwhistle in Berkshire, England, using a Meade 12-inch Schmidt-Cassegrain telescope.
The authors are grateful for the assistance given by Gerard Faure and John Greaves in the preparation of this paper: John for his analysis of LONEOS
and 2MASS data and drawing our attention to the formula for the calculation of V magnitude, and Gerard for his encouragement in developing the methodology and suggesting its applicability to measurement of the absolute magnitudes of asteroids.
It is sobering to consider that in the five weeks separating the discoveries of Ikeya-Zhang and Snyder-Murakami, IAU Circulars announced seven more comet finds by LINEAR and LONEOS
These stars have been calibrated against nearby LONEOS
Those comets discovered using data from space missions or professional surveys, such as SOHO, LINEAR, and LONEOS
, do not qualify.
